Hey beat.k,
I updated to version 123. WordPress no longer displays an error message, but the calendar is not always displayed on the website. It doesn’t matter whether I integrate the calendar via shortcode or widgets, it usually only displays once and then disappears.
I also sent an email.
Do you need more information?
My WordPress Version 6.9 and the Twenty Twenty-Three Theme Version: 1.6
Thanks for the quick fix !
Version 1.2.3.1 is running without any error messages.
Same here. After updating to 1.2.3, the page crashes / critical error.
WordPress Version: 6.9-de_DE
